“Post-Quantal Garden” Annotated

The Post-Quantal Garden is a work of speculative fiction based on J.G. Ballard’s short story “The Terminal Beach” first published in 1964. Set within Donna Haraway’s climate-changed Chthulucene, the work is intended as an elliptical rumination on the history of nuclear testing in the Pacific, bio-hacking, tropicality, and apocalyptic narrative. Moving between historical fact and speculative fiction, the story takes the form of a scholarly introduction to and contextualization of fictional passages from an imaginary journal supposedly found during the very real radiological clean-up of Enewetak Atoll. Enewetak, an atoll in the Marshall Islands group, was used by the US for nuclear testing and was the site of operation Ivy-Mike, the first fusion bomb test, and is the setting for Ballard’s Terminal Beach.

Background gamma radiation and soil activity measurements in the northern Marshall Islands

We report on measurements of external gamma radiation on 9 islands in 4 atolls in the northern Marshall Islands, all of which were affected by the US nuclear testing program from 1946 to 1958 (Enjebi, Ikuren, and Japtan in Enewetak Atoll; Bikini and Enyu in Bikini Atoll; Naen in Rongelap Atoll; and Aon, Elluk, and Utirik in Utirik Atoll). We also report americium-241, cesium-137, plutonium-238, and plutonium-239,240 activity concentrations in the soil samples for 11 islands in 4 northern atolls (Enewetak, Japtan, Medren, and Runit in Enewetak Atoll; Bikini and Enyu in Bikini Atoll; Naen and Rongelap in Rongelap Atoll; and Aon, Elluk, and Utirik in Utirik Atoll) and from Majuro Island, Majuro Atoll in the southern Marshall Islands. Our results show low external gamma radiation levels on some islands in the Enewetak Atoll and Utirik Atoll, and elevated levels on Enjebi Island in the Enewetak Atoll, on Bikini Atoll, and on Naen Island in the Rongelap Atoll. We perform ordinary kriging on external gamma radiation measurements to provide interpolated maps. We find that radionuclides are absent from all Majuro soil samples, and that they are present at highest activity concentrations in samples from Runit and Enjebi islands (Enewetak Atoll), Bikini Island (Bikini Atoll), and Naen Island (Rongelap Atoll). We contextualize all results by making comparisons between islands and to various standards, as well as to regions of the world affected by nuclear accidents. We also discuss implications for informed decision-making by the Marshallese and local atoll governments and their people on issues pertaining to island resettlement.

Coral reef inhabiting tubeworms (Polychaeta: Serpulidae) from Enewetak, Kwajalein, Rongelap and Utirik Atolls, Marshall Islands

The coral reef inhabiting tubeworms from the Marshall Islands have been studied by few authors mainly by samplings in Enewetak Atoll. We report several new records of serpuline and spirorbine tubeworms from Enewetak Atoll as well as from Kwajalein, Utirik and Rongelap Atolls. Twenty-one species of Serpulinae and seven species of Spirorbinae are described and illustrated with line drawings, colour and/or scanning electron microscopy photographs.Neodexiospira turritanom. nov. is proposed to replaceNeodexiospira preacuta. Enewetak Atoll still represents the most species-rich atoll in the Marshall Islands but this is most likely the result of a greater sampling effort in this atoll for the last few decades.
